The Mundra Thermal Power Plant is located in Mundra, Gujarat, India. It has a total capacity of 4,620 MW distributed across 9 units, making it one of the largest coal-based thermal power plants in the world. The plant sources coal primarily from Indonesia and water from the Gulf of Kutch. It uses a closed-cycle cooling system with seawater and has transmission lines to evacuate power to other parts of Gujarat and Haryana. The plant aims to utilize all fly ash produced and uses seawater-based flue gas desulfurization to reduce emissions without chemicals.

2. Introduction
 A thermal power station is a power station in which heat
energy is converted to electricity. Typically, water is heated
into steam, which is used to drive an electrical generator.
 Mundra Thermal Power Station is located at Mundra
in Kutch district in the Indian state of Gujarat.
 The power plant is one of the coal-based power
plants of Adani Power.
 The coal for the power plant is imported primarily
from Bunya, Indonesia.
 Source of water for the power plant is sea water from the Gulf
of Kutch.
 It is the world's 11th-largest single location coal-based thermal
power plant as well as India's second largest operational
power plant after NTPC Vindhyanchal.

3. Specifications

4.  Design and development
 The Mundra plant sets global benchmarks for power producers in terms of
size, efficiency and sustainability.
 Despite its enormous capacity, the facility stands unique in the world when
compared with area per MW.
 Located on a very optimized layout of 734 Acres alongside auxiliaries like
cooling towers, 47 MLD desalination plant and flue gas desulfurization plant.
 Power Evacuation
 To help the state and region utilities evacuate electricity from the plant and into the grid, Adani
Power had constructed two power lines.
 The 433 km, 400 KV transmission line to transmit 1000 MW from Mundra to Dehegam in
Gujarat.
 The 989 km, 500 KV high voltate Direct current (HVDC) bipole line with the capacity to
transmit 2500 MW from Mundra to mohindergarh in the northen state of Haryana.

5.  Fuel
 At full load, the plant consumes about 55,000 mt of coal per day,
though its yearly consumption is between 16 and 17 million mt.
 It runs on blended subbituminous coal, about 70% imported from
the Adani coal mine in Bunyu, in Indonesia’s East Kalimantan
province, and the rest from the public sector Mahanadi Coalfields
in the eastern Indian state of Odisha.
 Water
 Mundra is India’s largest TPP to function off a sea-water based
closed- cycle induced draft circulating cooling water system.
 The system draws on sea water that is recycled upto 4 times,
conserving water & requiring a smaller discharge pipeline into the
sea than an open- circuit cooling system.
 Though seawater is used for the cooling system, other Auxillary
systems use sea water purified by a reverse osmosis plant, that can
produce 47 Million litres of fresh water every day

6.  Ash Management
 They established and commissioned an Ash bagging unit to
achieve 100% Fly Ash utilization.
 Each machine has an operational capacity of 18 TPH and
the unit operates three such machines giving it a total
capacity of 54 TPH.
 Environmental Controls
 The FGD system, supplied by Alstom India, requires only
seawater as the adsorbent (no alkaline chemicals) to reduce
sulfur emissions.
 Its simplified structure comprising an adsorption tower,
seawater supply pump, and aerator renders operation and
maintenance (O&M) easy.

7.  Advantages
 Making Energy from Thermal Power plants is easy.
 The fuel used (coal) is cheap.
 Thermal Power Plant can be set up anywhere near fuel and water supply.
 It requires less space as compared to the hydroelectric power station.
 Disadvantages
 As thermal power plants involve the production of large amounts of smoke and fumes, these affect the
atmosphere.
 The overall efficiency of the power plant is low.
 The maintenance cost is expensive.
 The water requirement for maintaining the temperature of the turbines is too much.

8.  Conclusion
 At present thermal power plant generation accounts approximately 70% of the total amount of
electricity produced around the world.
 Thermal power generation, which uses fossil fuels, causes more CO2 emission than other
power generation method.
 We should optimize development of coal fired thermal power plant in geographical clusters
 Promote the development of thermal power plant in coastal areas.
